That way, the page is self-contained as it is, but requires no bundled binary code to serve the site. It is actually safer security-wise.
The vendored script can be as simple as this:
const site = {
"path-1": "<!DOCTYPE html><html> ... </html>",
"path-2": "<!DOCTYPE html><html> ... </html>",
// More paths
}
function attachListeners() {
for (const [path, html] of Object.entries(site)) {
document.querySelector(`a[href=${path}]`).onclick = () => {
document.documentElement.outerHTML = html
attachListeners()
}
}
}
document.addEventListeners("DOMContentLoaded", attachListeners)
